Fix #1259 : Enable parenthesizing for andor autocorrect

This change allows rubocop to parenthesize method calls so that
`method a,b or method c` can be autocorrected to `method( a,b ) || method( c )`
You'd need to create `Range` objects where you calculate the begin position and end position. It's decidedly more tricky, but I think you can find examples of it if you search for `Range.new` in other cops.
